SYRACUSE, N.Y. -- Aerial spraying of nearly 23,000 acres of land in Oswego County for mosquitoes finished Saturday, the county health department said.

The spraying included areas in the towns of Hastings, Mexico, New Haven, Palermo and Volney. Took two days because of the vast amount of land targeted.

The health department did aerial spraying a week ago, but decided to do more after finding additional mosquitoes infected with the potentially deadly eastern equine encephalitis virus in the northern part of the town of Palermo.
